Spirit bottle cap CW key

By OH6DC

Too much alcohol is bad for health and CW skills. Therefore it is maybe advisable to only buy spirit for using the bottle as a telegraph key.
(Use the liquid inside for cleaning the contacts of your other CW keys.)
Follow these modification instructions:

Attach
two strips of aluminium tape to bottle threads. Then connect the keying
wires by using a cable tie around the bottle neck.

For
improved keying performance, aluminium tape should be added inside the
cap (right side) as well as a piece of insulation tape (left side).
